I don't have wod beta or tried anything either. I pretty much know whats on mmochamp about garrisons.
From what i understood you are required to grind various materials for use in your garrison to boost various things, such as profession benefit.
Which will sadly be a big part in it as you will have to upgrade items twice and sorta progress trough the various professions.
I thought the mats grind + turn ins + missions or whatever it turns out to be would be like made for you to code and implement

As i have all professions + double of some and that's excluding my farmer accounts, i kinda feel the need for something automation as to not get overwhelmed.
Around prepatch beta starts to get sold for gold in trade, if i get a chance ill pick you up a key
